| 英文摘要 | The influences of different buffer gas, neon and helium, on ~(199) Hg~+ clock transition are compared in trapped ~(199) Hg~+ linear trap. By the technique of time domain’s Ramsey separated oscillatory fields, the buffer gas pressure frequency shifts of ~(199) Hg~+ clock transition are measured to be (d f/dP_(Ne))(1/ f) = 1.8 × 10~(-8) Torr~(-1) for neon and(d f/dP_(He))(1/ f)= 9.1 × 10~(-8) Torr~(-1) for helium. Meanwhile, the line-width of~(199)Hg~+ clock transition spectrum with the buffer gas neon is narrower than that with helium at the same pressure. These experimental results show that neon is a more suitable buffer gas than helium in ~(199) Hg~+ ions microwave frequency standards because of the 199 Hg+ clock transition is less sensitive to neon variations and the better cooling effect of neon. The optimum operating pressure for neon is found to be about 1.0 × 10~(-5) Torr in our linear ion trap system. |
